The so-called WHOIS details of each registered domain include information regarding the registrar company, the registration and expiration dates, and also the names, phone number, postal address and email address of the owner, the admin and the tech/billing person. WHOIS is a specific protocol that permits you to retrieve all this information through a command line or using one of the numerous websites which provide WHOIS lookup services. All info must be up-to-date in accordance with the policies of ICANN, the Internet Corporation for Assigned Names and Numbers. If some of the info is not accurate, the domain name might be reported and the result may be its deletion or losing its ownership. A number of country-specific domain name extensions have specific limitations for the modification of their WHOIS info, but in the general scenario any detail can be edited easily and at any moment. Such an adjustment will show up on lookup Internet sites within 24 hours.
